When you drape your asscheeks over an occupied bathroom or dressing room stall and take a fat shit on the stall occupant.
Sean was kicked out of Sears after he flooged on a small child early last Monday. Caleb was kicked out of JC Pennys for flooging on a man putting on pants in the changing room.
Flalooping is, in essence, the act of stopping yourself from Flalooping when you're Flalooping. You must first recognize that you are in fact Flalooping, and then stop and go back to normal. The best way to stop someone else from Flalooping is by yelling something along the lines of "I see that you're Flalooping right now, and it needs to stop!" The person who was Flalooping will instantly apologize and return to what they'd been doing prior to being called out for Flalooping.
Girl: *Flalooping* So this one time, when I was at the mall...
Guy: Excuse me, Miss? I hate to be rude, but you're Flalooping and it's making me uncomfortable.
Girl: Oh crap! I'm so sorry! *Stops Flalooping* So anyways, so this one time, when I was at the mall...
Pronounced 'flan-jing', the act of mixing two audio signals together, with one being delayed by a small and slowly changing period producing an output signal with peaks and troughs in a harmonic series. Flangers are similar to phasers (phase-shifting, beyond the scope of this definition) however, if you listen intently enough, you can hear the difference.
The flange effect can best be described (to those who never studied wave mechanics) as a jet sound; sounds like a jet aircraft passing by the listener. Phasing on the other hand sounds much more alien and "other-worldly".
While used in all sorts of different music, flangers are most heavily used in psychedelic and dreamy music where strong harmonics and a "wall-of-sound" depth are often sought - used with good reason too, flanging sounds insanely beautiful when you're as high as a kite. ;)
I was listening to Slowdive's Machine Gun shortly after returning from another galaxy. Coming down, the flanging was simply too beautiful for my human ears, so I cried and reassessed existence.
